setting up uv based package management

[rororowyourboat]

Context

Python dependency management in MSML is currently implicit and environment-dependent. This leads to:

• Inconsistent local setups
• Slower installs
• Friction between local dev, CI, and containers

Using uv would provide fast, reproducible dependency management and clearer workflows.

---

Goals

• Make dependency management explicit and reproducible
• Align local development, dev containers, and CI
• Reduce setup time and environment drift

---

Scope

• Introduce uv as the recommended package manager
• Add pyproject.toml / uv.lock (or equivalent)
• Update setup and contribution docs to use uv
• Ensure compatibility with CI and dev containers

---

Deliverables

• uv configuration committed to the repo
• Updated setup instructions
• CI updated to install dependencies via uv

---

Non-Goals

• Supporting multiple package managers long-term
• Solving packaging for downstream users (initially)
